All the tools you need for your skateboard--9/16", 1/2", and 3/8" wrenches, 1/2" socket, both Phillips and Allen screwdrivers, and even a grip tape file. The chrome vanadium hardened steel Alpha tool is ultra strong and ultra compact--only 3" long. The Alpha tool extends to nearly 4 1/2" so you can get a good grip when cranking down on your kingpin. The 1/2" socket is great for getting into those deep old school and long board wheels. The removable Phillips and Allen screwdriver bit can be inserted into the side of the screwdriver for easy use.
